This study presents Raman spectra of carbonates on a carbonaceous chondrite, Yamato (Y) 980115. Y 980115 is an Antarctic meteorite and is originally classified as CI1-type. Since CI1-type meteorites are expected to record information of aqueous alteration of carbonaceous matters in the primitive solar photosphere or planetesimals, extensive studies have been performed. Among a variety of minerals on meteorites, carbonates are one of environment indicators because its cation composition depends on thermochemical properties of the aqueous solution when they were precipitated. Although the minerals on meteorites are usually identified by elemental composition analysis techniques such as backscattered electron imaging, these techniques have a drawback that they lack information of crystal structures so that it is difficult to distinguish some minerals such as ordered or disordered dolomite (CaMg(CO
